CAR-COUPLINGJ SPECIFICATION forming part of Letters Patent No. 364,798,dated June 14, 1887.

Application filed October J0, 1886. Serial No. 2lG,746. (No model.)

To all whom it may concern:

Be it know that we, PERRY BRowN and DANIEL E. DOHERTY, both citizens ofthe United States of America, residing at Louisville, in the county ofJefferson and State of Kentucky, have invented certain new and usefulImprovements in Car-Couplings, of which the following is aspecification, reference being had therein to the accompanying drawing,in which Figure 1 represents a vertical central longitudinal section ofa coupling constructed according to our invention; Fig. 2, a rear endView of the same; Fig. 3, a reversed plan thereof, and Fig. 4 a similarsection to that in Fig. 1 of the mouth of the draw-head with the link indifferent positions.

This improvement relates to that style of coupling in which the pinrests on a support which is pushed away by the link as it enters thebuffer-head; and the inventionconsists in v the peculiar construction,arrangement, and

combinations of parts hereinafter more particularly described, and thendefinitely pointed out in the claims.

Referring now to the details of the drawings, which show the preferableform of our improveinent, A represents the buffer-head, having the usualopening to receive the link, and arear extension, at, which passesthrough a yoke, 13,. secured to ears 0 0, attached to the trussrods,OG,running under the car; or, if preferred, the yoke may be securedin any suitable way to any convenient part of the framework of the car.Around the extension a are set (one on each side of the yoke) the spiralsprings D D, the latter being held on by anut, E, and keyor wedge F, bywhich construction the head A is elastically connected with thetruss-rods O G, and through them with the car.

The head has a peculiarly-shaped recess, a, which is partially closed atthe bottom by a stop,G, which thus forms the bottom of the recess a,and-which has an angular notch, g, at one end, that rests against theangular corner of the back wall of the recess, as shown, and is heldthere by a pin, H, that passes through lugs a, formed on the bottom ofthe drawhead, and through the stop G.

In the recess a is set a peculiarly-shaped block or dog, I, the lowerend of which rests on the stop G, and its top supports the coupling-pinJ, which may either be of the ordinary variety or be provided with aslight groove, j, at or near its lower end.

The face of the upper edge of the stop G is preferably formed ofthecurved shape shown, with two indentations, g g, and the dog I hasalso two indentations, it, in its face, audits top is inclinedbothtoward the front and rcar of the draw-head, as shown in Fig. 1.

The operation is as follows: When two cars are to be coupled, the pin israised, which will allow the dog I to assume the position shown in fulllines in Fig. 1, when the pin will rest upon it, as shown in the samefigure. As soon as the link (represented in dotted lines in Fig. 1) fromthe other car enters, it pushes the dog I, and then the pin will dropdown into the link, as shown in dotted lines in Fig. 1 and in full linesin Fig. 4, in which position the pin will be securely held, for thegroove j in the bot-' tom of the pin will prevent any accidental risingof the pin far enough to nncouple cars.

Owing to the peculiar configuration of the acting face of the stop G andthe shape of the dog I, the link may be held in different positions.Supposing that the coupling shown in Fig. 4 is on a car that is to becoupled to another one having a low coupling, the link may be left inthe position shown in full lines, so as to readily enter a low coupling.If, however, the opposite car has a high coupling, the outer end of thelink can be raised, and by pushing it back slightly the dog will be madeto assume .the position shown in dotted lines in Fig. 4,

and then thelink will be held in the position shown in dotted lines bythe weight of the dog,

so as to enter a high coupling.

It will be seen that our draw-head is a simple casting cored out toreceive the pin-link and dog, which latter is put in from below andsecured therein by the stop G, which latter is held in place by a simplepin, so that it can be easily removed or replaced should occasionrequire the same.

From the above it will be seen that we have produced an automaticcoupling that is easily made and durable, as it has but few piecesonethat can be readily coupled to either high or low cars, as desired, andone that is notlikely to become uncoupled accidentally.

What we claim as new is- 1. The combination, with the draw-head A, pinJ, and removable stop G, of the dog I, resting on said stop, and the pinj, adapted to rest on the dog, substantially as described.

2. The combination, with the draw-head A, pin J, and stop G, havingindentations gg, of the dog I, having indentations i i in its face,whereby the link may be held in different positions by the weight of thedog, substantially as described.

3. The combination, with the draw-head A- and pin J and the removablestop having an indented face and a shoulder, g, of the dog I, resting onsaid stop, substantial ly as described.

4. The combination, with the draw-head A, having a recess closed at thetop, of the pin J, 20 the removable stop G, having an indented face, andthe dog I, also having an indented face, all construct-ed and arrangedsubstantially as shown and described.

In testimony whereof we affix our signatures 25 each in presence of twowitnesses.
